He went down to earth to experience calamities, but he didn't want to meet the Demon Lord, and he didn't know the shame and fell in love. It wasn't until he returned to the fairy world that he realized that the things he did with the Demon Lord in the mortal world were really shameful. No! You must kill the Demon Lord with your hands! Atonement for yourself! Humans and demons are at odds with each other! How can we be together!
Purpose: Should he be despised by thousands of people because he is a demon? Since the world wants to leave me behind, then I will leave this world alone! But only you, I will never let go!
